The TAC hospitalisation reports are based on claims accepted by the TAC from people with injuries sustained in transport accidents in Victoria, where the injured person was admitted to hospital within 7 days of crash. Excluded are denied and pending claims, and claims related to crashes occurring interstate.

TAC hospitalisation claims data is updated monthly from TAC claims databases. A six-month reporting lag is applied to the data, allowing for claims to be lodged and processed, and hospital invoices to be received and processed. Claims are reported by claim acceptance date. Data is subject to revision as additional information about known claims is received, and as new claims are received and processed.
